Asymmetric copolymerisation

Iggo and coworkers have studied the asymmetric copolymerisation of styrene with CO catalyzed by Pd-(R,S)-BINAPHOS complexes under both diffusion- and... 

Relevant mechanistic aspects of the asymmetric copolymerisation of propene with CO have been disclosed by an NMR study of subsequent reactions of the complex [Pd(Me)(NCMe)((R,S)-BINAPHOS)]BAr4 with CO and propene (Scheme 7.23) [7a-f],... 

The asymmetric copolymerisation of carbon dioxide and cyclohexene oxide was realised by the Sugimoto group with chiral binuclear aluminium p-ketoiminate 57 as the catalyst (Scheme 19.65). The asymmetric copolymerisations were found to be significantly dependent on the size of epoxide, temperature, and kind/amount of activators.
